BENCH-VISE To all whom it may concern:

Be it known that I, PURNA F. VVRAY, a

citizenof the United States, residing at .Sedalia, inthe county of Pettis and State of Missouri, haveinvented a new and useful Bench-Vise, "of whichthe following is a specification.

' This invention relatesto bench vises; and has for its obj ect to provide a simple, strong and self acting vise arranged to be fastened wholly on the top of a bench and designed to grasp quickly and hold firmly material of such width as will enterthe mouth of the vise.

T he tool comprises two principal members, a straight piece firmly attached to the top of a work bench at the edge thereof, and an "angular member hingedon the top of the bench at any desired distance from the fixed member. The adjustment of the parts is such that the greater the pressure on the work in the vise the tighter the work is held.

' Besidesforming a simple and strong vise,

. fee

- teethor serrations 1 on its terminal.

one orboth membersthereof are designed to serve asstops or work holders.

With these and other objects in view the J invention consists of the novel combination and arrangement of parts hereinafter described and claimed and illustrated in the accompanying drawing forming a p art of this I specification, in which: I

. Figure 1 1s a perspective view of the 1mproved tool applied to carpenters bench, a portion'only of which is shown; Fig. 2 a crosssectional view of the vise and a art of the'bench, the section being taken tirough the pivot of, the movablemember, and Fig. 3 is a'plan view of the pivot of the movable memberfof the vise, with the head. of the pivot bolt removed.

flange 5 perpendicularto the bottom plate 20 and extending from end to end of the same. The rear end of the flange 5 near the serrationsdandythe upturned end 3 of the plate 20 are inclined downwardly to form in Specification of Letters Patent.

part said serrations. Between the bottom plate 20 and the perpendicular flange 5 thereon are a number of integral brackets or braces 6 which strengthen the member 1 and enable the upright flange 5 to withstand the strains of such work as willbe forced against it. Holes are made in the bottom plate 20 to receive fastening screws 7 which secure the member 1 to the work bench with its outer edge at the edge of the bench A and parallel therewith.

T he member 2 consists of an angular lever having a forward arm 8 and a rearward arm 9 at an angle to each other, and, at the point of meeting of the two arms is a stud or enlargement 10, integral with the plate 12 and flange 13, for the pivot bolt 11 on which the member 2 rocks in a horizontal plane. The member 2 like the member 1 is made with a bottom plate 12 and an upright flange 13 perpendicular to said plate and facing the flange 5 on the fixed member 1. A number of brackets or braces 14, similar to those 6 on the member 1, connect and strengthen the plate 12 and flange 13 of the member 2.

T he stud or enlargement is semi-circular in shape and as high as the flange 9, through which enlargement two circular holes 15 and 16 of equal diameter are made, a short distance apart and perpendicular to the bottom of the member 2. The axes of the holes 15 and 16 he in the continuation of the line bisecting the angle formed by thetwo arms 8 and 9 of the member 2. Between the two holes 15 and 16 is a straight channel 17 narrower than said holes and centrally divided by the line connecting them. Rotatable in either of the holes 15 and 16 is the bolt 11 forming the fulcrum for the member 2. Where the bolt 11 passes through the enlargement 10, it is flattened on opposite sides so as to enable the bolt to pass freely through the channel 17 from hole to hole when turned to the proper position. bolt 11 passes through the top board of the bench and screws into a'nut 18 on the under side, said nut having an angular projection 19 on its upper side to enter a similarly shaped opening in the bottom of the bench which will prevent the nut turning. The

rear end of the member 2 is provided with The lower end of the serrations 20 on the flange 13 which thus stand vertically whilethe serrations 4 on the member 1 are disposed horizontally. When set in position, the forward. arm 8 of the member 2.

member 2 converges toward the member 1 and extends diagonally across the forward end thereof, if said members are not set too far apart.

The operation of the vise is very simple. After securing the member 1 on the edge of the bench, the member 2 is pivotally fastened on the top of the bench a distance from the member 1 to easily admit between them material which rarely runs over a certain thickness. When a piece of wood of maximum thickness or less is placed between the flanges 5 and 12 and pushed forward, its front end will strike the angular arm 8 and turn it on its fulcrum until the rear end of the arm 9 strikes the board. From this point the harder the board is forced forward the greater will be the side pressure fromthe end of the arm 9.

Should it be necessary to hold a piece of material slightly wider than the vise is set for, it is only necessary to turn the bolt by a screw driver until its flattened sides are placed parallel to the sides of the channel 17 and then push the member 2 sidewise until the hole 15 embraces the bolt 1 1 which is then turned slightly to prevent the escape of the The space between the flanges 5 and 13 will, by this action, be increased the distance between the centers of the holes.

What is claimed is:

1. A bench vise comprising a fixed memher having a straight working face and a horizontally serrated rear end to form a work stop, a rocking member formed of two horizontally disposed arms at an angle to each other and in the same plane as the fixed member, the forward arm adapted to pass at an angle across the forward end of the fixed member the rearward arm spaced from the fixed member and provided with a vertically disposed serrated work stop in line With the rear of the fixed member, and a fixed pivot bolt passing through the rocking member and the work bench.

2. A bench vise having a fixed member and an angular rocking member spaced apart and adapted to be secured to a work bench, an enlargement at the angle of said rocking member provided With two spaced circular openings connected by a channel, and a pivot bolt fitting said circular openings with reduced portions on opposite sides to pass through said channel, whereby the axis of either circular opening may be made the axis of rotation of the rocking member, and the distance between said members changed.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
